Transformerless chipset enables higher power density AC-DC converters

Using switching capacitors for power conversion, and by transferring power across a capacitive isolation barrier, the MxC 300 chipset released by Helix Semiconductors enables the replacement of traditional transformers, which are bulky and less efficient. As a result, AC-DC power supplies up to 65W can realize up to 20x power density improvement over traditional transformer-based architectures – with average efficiencies of greater than 94 percent.
